See a solution process below:

Find the prime factors for each number as:

#25 = 5 xx 5#

#36 = 2 xx 2 xx 5 xx 5#

Now identify the common factors and determine the GCF:

#25 = 2 xx 2 xx color(red)(5) xx color(red)(5)#

#100 = 2 xx 2 xx color(red)(5) xx color(red)(5)#

Therefore:

#"GCF" = color(red)(5) xx color(red)(5) = 25#
